What is a polynomial?
Back
A polynomial is a mathematical expression consisting of variables (also called indeterminates) raised to whole number powers and coefficients. It can be expressed in the form: a_n*x^n + a_(n-1)*x^(n-1) + ... + a_1*x + a_0, where a_n, a_(n-1), ..., a_0 are constants.

What is the standard form of a polynomial?
Back
The standard form of a polynomial is when the terms are arranged in descending order of their degrees. For example, 4x^3 + 2x^2 - x + 5 is in standard form.

What is the degree of a polynomial?
Back
The degree of a polynomial is the highest power of the variable in the expression. For example, in the polynomial 3x^4 + 2x^2 - 5, the degree is 4.

FLASHCARD QUESTION
Front
How do you add polynomials?
Back
To add polynomials, combine like terms. For example, (3x^2 + 2x) + (4x^2 + 5) = (3x^2 + 4x^2) + (2x) + (5) = 7x^2 + 2x + 5.
6.
FLASHCARD QUESTION
Front
What is the product of two polynomials?
Back
The product of two polynomials is found by multiplying each term in the first polynomial by each term in the second polynomial and then combining like terms. For example, (x + 2)(x + 3) = x^2 + 3x + 2x + 6 = x^2 + 5x + 6.
